03. Combinatorial Therapeutic Effect(s)
Synergistic Effect
Hide/Show
Drug(s) whose efficacy can be enhanced by this phytochemical
Hide/Show
Combination Pair ID: 1
Pair Name Camptothecin, Sorafenib
Partner Name Sorafenib
Disease Info [ICD-11: 2C12] Hepatocellular carcinoma Investigative
Biological Phenomena Induction-->Ferroptosis
Gene Regulation Down-regulation Expression ABCG2 hsa9429
Down-regulation Expression MT1G hsa4495
Down-regulation Expression NFE2L2 hsa4780
Down-regulation Expression SLC7A11 hsa23657
Down-regulation Expression SQSTM1 hsa8878
In Vitro Model Hep-G2 Hepatoblastoma Homo sapiens (Human) CVCL_0027
Huh-7 Adult hepatocellular carcinoma Homo sapiens (Human) CVCL_0336
Result The synergetic combination significantly increases lipid peroxidation and iron concentration, decreases TAC, GPX4 and GR activity, and reduces the expression of both Nrf2 and SLC7A11. The downregulation of Nrf2 expression has a vital role in the reduction of resistance mediators to sorafenib against HCC cells like (p62, MT1G, and ABCG2) and improves the cellular uptake of sorafenib. The current study provided evidence that Nrf2 inhibition by CPT improves sorafenib's sensitivity and reduces sorafenib's resistance via the augmentation of sorafenib's ferroptosis action.
